Abstract: The power controller has a switch (10) in series with the load (2). The switch may be a gate turn-off thyristor (GTO), made bi-directional by a rectifier bridge. Alternatively the switch can be implemented with two anti-parallel GTO thyristors. The switch is normally closed and is controlled so that it opens at each alternation of the supply. The control (3) of the thyristor is provided through a train of pulses that are at double the supply frequency. A capacitor (C) in across the switch damps the switching transient spikes. The control allows the early part of the alternating cycle through and blocks the later part, the reverse of the load waveshape using conventional triac control.

Abstract: The converter receives an AC voltage (Vac) between an input terminal (11) and a reference terminal (12) and supplies two DC voltages with opposed polarities (V+,V-) to the terminals of a first (C1) and second (C2) capacitors, of which a common terminal is connected to the reference terminal. The converter contains: - a first uni-directional switch (K) connected between the input (11) and a circuit node (13); - a third capacitor (C3) connected in parallel with the first capacitor (C1), between the node (13) and the reference terminal (12); - a circuit including a second switch (K') for connecting the second capacitor in series with the third capacitor (C3) when the second switch (K') is closed, and; - a control circuit (15) for closing the first switch only at the start and end of alternate given polarities. The second switch (K') being opened when the first switch (K) is closed. .
